Each pack BMS of the plurality of pack BMSs, in an opening control condition of the plurality of positive relays and the plurality of negative relays, may be configured to determine whether the positive relay of the pack BMS's corresponding battery pack is stuck-closed based on a first battery pack current flowing to the pack BMS's corresponding battery pack.",
